Hi barney,
Have seen the same today. Afaik ISO-8859-1 (latin1) does NOT know the € character. I think ISO_8859-15 or UTF-8 (and similar encodings) should know it.
Currently the table attribute (currencies.curr_symbol) is still latin1 which is non optimal as well. So I would say this is/should be a feature request to FA team.
